A bobbin wound coil for an electromagnetic coupling includes a bobbin having a cylindrical body, end flanges disposed at opposite ends of the body and a terminal connector defining a central cavity bordered, in part, by inner and outer walls and a side wall extending between the inner and outer walls. A coil has a beginning portion extending through first openings in the inner and outer walls, an end portion extending through second openings in the inner and outer walls, and a center portion wound about the bobbin body. The first and second openings in the inner wall divide the inner wall into first and second circumferential end sections and a center section. A portion of one of the circumferential end sections and the center section is spaced from the side wall to define a recess configured to receive one of the beginning and end portions of the coil.
